  2. Olkiluoto Nuclear Power Plant - Wikipedia

    en.wikipedia.org/wiki/Olkiluoto_Nuclear_Power_Plant

    An incident occurred at unit 2 on 10 December 2020 at 12:22. Because of valve repair work, excessively hot water flowed to the reactor water clean-up system filters. The hot water dissolved materials from the filters. When the clean-up system was restarted, the dissolved materials flowed to the reactor core, where they became radioactive. This ...

    en.wikipedia.org/wiki/Steam_generator_(nuclear...

    In commercial power plants, there are two to four steam generators per reactor; each steam generator can measure up to 70 feet (21 m) in height and weigh as much as 800 tons. Each steam generator can contain anywhere from 3,000 to 16,000 tubes, each about .75 inches (19 mm) in diameter.

  4. Steam generator (boiler) - Wikipedia

    en.wikipedia.org/wiki/Steam_generator_(boiler)

    A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube , arranged as a single, or monotube , coil. Circulation is once-through and pumped under pressure, as a forced-circulation boiler . [ 1 ]

  5. Boiler blowdown - Wikipedia

    en.wikipedia.org/wiki/Boiler_blowdown

    A steam boiler evaporates liquid water to form steam, or gaseous water, and requires frequent replenishment of boiler feedwater for the continuous production of steam required by most boiler applications. Water is a capable solvent, and will dissolve small amounts of solids from piping and containers including the boiler.

  6. Dresden Generating Station - Wikipedia

    en.wikipedia.org/wiki/Dresden_Generating_Station

    Dresden 1 Nuclear Flow Diagram featured a secondary steam generator for load following. The reactor featured a dual cycle, with steam coming from both the stream drum and steam generators. This made for rapid response to changes in power demand. Reactor power was regulated by actuation of the secondary admission valve by the turbine's governor.

  7. Steam generator - Wikipedia

    en.wikipedia.org/wiki/Steam_generator

    Steam generator (auxiliary boiler), a steam-powered boiler used on ships to produce a low-pressure steam, heated by a high-pressure steam supply rather than a flame. Steam generator (boiler), an oil- or gas-fired boiler, based on a low-water content monotube coil. Steam generator (nuclear power), a heat exchanger in a pressurized water nuclear ...

  8. Supercritical steam generator - Wikipedia

    en.wikipedia.org/wiki/Supercritical_steam_generator

    A supercritical steam generator is a type of boiler that operates at supercritical pressure and temperature, frequently used in the production of electric power. In contrast to a subcritical boiler in which steam bubbles form, a supercritical steam generator operates above the critical pressure – 22 megapascals (3,200 psi ) and temperature ...

  9. Electric steam boiler - Wikipedia

    en.wikipedia.org/wiki/Electric_steam_boiler

    Water from the system or holding tank is then run over or near this hot element in a pipe or tank, heating the water to a suitable temperature, then making the water hot enough to boil and become saturated steam, [1] at which point the saturated steam is transported to wherever it is needed via the steam pipes that exit the body of the electric ...
